Patented Oct. 8, 1907;

To all whom it may concern:

Be itknown that I, SAMUEL GoLDEN, acitizen of thl United States, residing at Buffalo, in the county of Erie and $tate of New York-,- have invented a new and useful Improvement in Hulls for Vessels, of which the following :is a specification. p 1

This invention relates to the hulls of vessels, par ticularly those which are propelled by screw propellers,

and has for its object to secure greater efiiciency and' speed, increase the stability and seaworthiness, facili tate maneuvering, and gain other advantages.

To that end my invention consists of a hull which has its bottom provided'with a hollow extension or fin,

having the. form or lines of a vessel and suitable for accommodating the propelling machinery, wholly or in part, said bottom extension or fin being shorter and narrower than the hull and beginning at a distance in rear of the stem or front end of the hull and terminating at a distance forward of the stem or rear end 'of the hull, sothat the bottom of the hull extends forwardly, rearwardly and laterally beyond this extension or hol- 10W fin.

In the accompanying drawings, consisting of two sheets: Figure 1 is a side elevation of a launch or-simiportion of the vessel. FigQ 5 is a-bottom plan view.

6 is a vertical cross section in line 66, Fig. 1, on an enlarged scale. Fig. 7 is a side elevation of a steam vessel provided with my improvement.

Like letters of reference refer to like parts in the. several figures.

A represents the hull of the vessel and B the hollow bottom extension or fin formed on the bottom of the hull and extending downwardly therefrom. This ex-.

tension or fin. has the form or lines of a vessel and is of less length and width than the hull and begins at a distance rearwardly from the front end or stem a of the hull. .Thefront end or steal b of the fin preferably made slanting, The finis preferably about half as long as the hull, and the front and rear overhang of the hull are each about, one-fourth the length of theghull,

,but these porpor'tions may be changed at desire. The

fin is made as narrow as circumstances will permit.

The stern or rear portion ofthe fin is provided with a stern tube 0 for the shaft 'of the propeller wheel D. E represents the rudder which is arranged underneath the bottom of the hull in rear of the propeller wheel and supported on a shoe e. The fin is hollow so-iar as may be necessary to accommodate the propelling machinery or parts of the same. The engine F is arranged in the fin on the floor members or plates f thereof and my project into the bull to a greater or less extent.

case of a steam vessel the boiler or boilers are arranged in the hullfas represented by dottcd line's inFig. 7.

' The floor plates or members 9 of thehull extend]? across the upper portion of thefin, Fig. 4, and connect and brace the parts of the bottom of the'h ll: i

which are located on opposite sid es of the fin.

The front portion h of the bottom oftho hull forwardly beyond or overhangs the front end b of thje fin, and the rear portion i of the bottomof the" extends rearwardly'beyond or overhangs the rear'e'nd b of the fin, these overhangs having about the same length or extent, so that the vessel is approximately balanced fore-and aft.- This balancing of the front and rear overhangs of the hull over the fin gives the wind about equal bearing or pressure on the front and rear ends of the hull, whereby the vessel is enabled to turn against thewind or with the wind with equal facility. The main hull is easily kept in a horizontal position with or without load, whereby maneuvering is rendered easy and certain under all conditions of water and weather. The hull is provided in its bottom in rear of the fin and over the propeller with; a well or port K which extends above the light water line and which is closed, preferably, by a removable bottom plate 1 and-a removable top plate l, either or both. Upon removing these plates the propeller can be inspected and minor repairs can be made on the same.

The bow wave 0r water which is displaced bytho front end of the finwhen being driven through the water is forced up against the forwardly overhanging bottom of the hull and tends to raise the same, while the water which is driven aft by the propeller wheel tends to raise the rearwardly overhanging portion of the vessel. The faster the boat is driven the greater is the tendency which is so developed to raise the 'hull, whereby the friction and resistance are. correspondingly reduced.

The propeller wheel is placed in a position underneath the hull where it will remain submerged in unbroken water under all conditions of load, weather and motion, thereby avoiding the severe shocks and strains to the-vessel and machinery when the screw or propeller works in a scaway alternately on a light load on being raised and on a heavy load uh I," ing lowered.

The propeller shaft is comparatively short, whereby given to the hull fin so that the water is parted and I least possible disturb- The hull fin presents a very small cross secallowed to fall back with the tion to the water through which it is driven, and

' big sea.-

.As the propeller wheel and rudder are always submerged in unbroken water they can be relied upon to properly perform their functions under all circumstances, and as the fin acts as a center board or pivot tothe hull and prevents the 'vessel from sliding sidewise when turning, or dril'ting to leeward under wind pressure, the vessel is enabled to turn on a very short radijhs, whether going forward or backward, and-to exelcute intricate evolutions quiekly and safely.

The fin forms an arch on the bottom of the hull whereby the latter is greatly strengthened and stiffened.

I claim as my invention:

The combination of a vessel hull having a hollow hori zontal bottom extension of less length and width than the hull, said extension heing overhung by the bottom of the hull at the front, 'rear and sides, the front portion of the extension sloping from the hottoni of the hull downwardly and rearu'ardly to the bottom of the extension, the front and rear ends of the extension being arranged at a distance rearu'ardly and forwardly of the front and rear ends of the hull,'and the bottom of the hull extending approximately at right angles outwardly from the upper ends of the sides of the extension. :1 propelling engine arranged with its lower portion in said extension, a'horizontal propeller shaft extending from said engine rear- \varclly through the extension, a propeller arranged at the rear end of said extension, and a rudder arranged in rear of said propeller underneath ihe overhanging holtuni or the rear portion of the hull, substantially as set forth:

'itnuss my hand, this 18th day of February, 1905.
